Abstract

The utility model discloses a suspension structure for automobile, comprising a swing arm(1), a sub frame vertical tube beam(3), a lining(4), a wheel installing loop(6), a sub frame front beam(7), a shock absorber(5) and a lower swing arm(9), wherein two linings(4) are provided with the two ends of the sub frame front beam(7) and connected with two sub frame vertical tube beam(3), the structure of the lower swing arm(9) is that two sides of a sub frame(8) are separately provided with a vertical diagonal stay(2), and one end of the vertical diagonal stay(2) is fixed on the swing arm(1), and the other end is connected with the lining(4). The utility model under the condition of fulfilling intensity can reduce the quality of parts and components, improve the utilization rate of fore cabin space, reduce the striking to the car body from non-spring loading quality, and improve the ease capability of automobile running. The utility model will be shrunk and deformed while being collided, thereby improving the energy absorption effect, dividing the energy absorption burden for car body while being collided.

Description

A kind of automotive suspension structure

Technical field

The utility model relates to automobile, and more particularly, the utility model relates to a kind of automotive suspension structure.

Background technology

At present, McPherson suspension system bottom arm assembly adopts the integral type A-frame arm more at present, and its structure is solid weldment, links to each other with subframe by 2, and A-frame arm mainly bears pressure.This structure has caused triangle arm volume bigger than normal, has taken the front deck space, arranges so the use of triangle arm more is unfavorable for front deck.And for compact car, front deck arrangement space itself is just very limited.Increased nonspring carried mass simultaneously, brought more impact, reduced the car load ride comfort to vehicle body.

The utility model content

Problem to be solved in the utility model provides a kind of automotive suspension structure, its objective is to alleviate component quality and improve space availability ratio.

In order to realize purpose, the technical scheme that the utility model is taked is: this automotive suspension structure that is provided comprises swing arm, the vertical Guan Liang of subframe, lining, wheel installing ring, subframe front cross rail, bumper and following swing arm, two linings are located at the two ends of subframe front cross rail respectively and it are vertically managed beam with two subframes and are connected, the structure of described swing arm down is for respectively being provided with a vertical hound in the both sides of subframe, vertically an end and the swing arm of hound are fixedly connected, and the other end connects with lining.

The coupled position of described vertical hound and swing arm is close wheel installing ring in swing arm, and vertically hound is above swing arm, and vertically the coupled position of hound and lining is below the vertical Guan Liang of subframe.

Described vertical hound two ends point of attachment and shaft be in-line not, and whole vertical hound has formed the bending of S.

Adopt technique scheme, the utility model is being satisfied under the strength condition, reduce the parts quality, help arrangement of suspension system, improve the front deck space availability ratio.Reduce nonspring carried mass, thereby reduced the impact that nonspring carried mass brings to vehicle body, improved the ride comfort of running car.Because crooked shape can produce shrinkage distortion when collision takes place, improve the energy absorbing effect simultaneously, the energy-absorbing burden of shunting vehicle body when collision.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a swing arm structure scheme drawing of the present utility model.

Number in the figure is: 1, swing arm, 2, vertical hound, 3, the vertical Guan Liang of subframe, 4, lining, 5, bumper, 6, the wheel installing ring, 7, the subframe front cross rail, 8, subframe, 9, swing arm down.

The specific embodiment

As Fig. 1 structural representation of the present utility model and the expressed structure of the present utility model of Fig. 2 swing arm structure scheme drawing of the present utility model, the utility model is a kind of automotive suspension structure, its form is the Mai Fuxun independent suspension, comprise that swing arm 1, subframe vertically manage beam 3, lining 4, wheel installing ring 6, subframe front cross rail 7,

bumper

5 and 9, two linings 4 of following swing arm and be located at the two ends of subframe front cross rail 7 respectively and it is vertically managed beam 3 with two subframes and be connected.By bumper 5 and body contact.

In order to alleviate component quality and to improve space availability ratio, the specific embodiment that the utility model is taked is: the structure of described swing arm 9 down is for respectively being provided with a vertical hound 2 in the both sides of subframe 8, vertically an end and the swing arm 1 of hound 2 are fixedly connected, and the other end connects with lining 4.Be rigidly connected swing arm under the triangle of a hollow of composition in this device with swing arm 1 by a vertical hound 2.Vertically hound 2 has certain length.Help to reduce the pendulum angle of the auxiliary connection vehicle frame 8 and the lining 4 of vertical hound 2 other ends, improve the life-span.Adopt technique scheme, the utility model is being satisfied under the strength condition, reduce the parts quality, help arrangement of suspension system, improve the front deck space availability ratio.Having reduced nonspring carried mass is unsprung weight, thereby has reduced the impact that nonspring carried mass brings to vehicle body, improves the ride comfort of running car.

Vertically the coupled position of hound 2 and swing arm 1 in swing arm 1 near wheel installing ring 6, and vertically hound 2 above swing arm 1, vertically the coupled position of hound 2 and lining 4 subframe vertically manage beam 3 below.Satisfying swing arm design under the optimization suspension system under the strength condition, be rigidly connected with swing arm 1 by a vertical hound 2, do not adopt the triangle arm and realized the function of triangle arm reducing nonspring carried mass effectively, more help arrangement of suspension system, improve the front deck space availability ratio.

Vertical hound 2 two ends point of attachments and shaft be in-line not, and whole vertical hound 2 has formed the bending of S.Because vertically hound 2 is crooked shape, car load is when bumping, and vertically deformation at first takes place hound 2, helps the absorption of collision energy, shunts the collision energy-absorbing burden of vehicle body, has improved the safety performance of car load.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
